78% Recycled Nylon 22% Spandex Thermal Brushed Ponte Roma Knit combines 78% GRS recycled nylon / 22% spandex with a Ponte Roma Knit construction. It is aimed at Leggings that require squat-proof coverage and recovery at the knee and seat, and the reason is straightforward: virgin nylon performance with a documented recycled content claim, so Thermal Brushed.

Why this construction works
Performance comes from three decisions: the yarn, the stitch and the finishing route. 78% GRS recycled nylon / 22% spandex supplies the base behaviour, a firm ponte roma double knit sets how air and moisture move, and finishing is kept deliberately light so the attributes survive washing.

Performance features
- Thermal Brushed: traps warm air while staying light enough for active use, measured by ISO 11092 thermal resistance.
- Hand and comfort: virgin nylon performance with a documented recycled content claim.
- Construction benefit: a clean, structured surface with enough hold for tailored athleisure.
- Consistency: GSM and width tolerance are locked per lot and recorded on the inspection sheet.
- Durability: performance is verified after repeated washing, not only as delivered.
Recommended applications
Specified mainly for Leggings, and suited to any programme where squat-proof coverage and recovery at the knee and seat is written into the brief. Designers use the same base for matching styles, which keeps colour continuity simple across a collection.

Dyeing, finishing and customisation
Dyeing runs on a controlled recipe with consolidated dye lots to hold shade continuity. Finishing options include wicking, antibacterial, soft touch and anti-pilling, applied after lab trials so the hand approved in sampling is the hand delivered in bulk.
Care instructions
- Machine wash at 30 degrees with mild detergent, no fabric softener.
- Dry away from direct heat and do not tumble dry hot.
- Cool iron on the reverse if needed, and avoid bleach.
Ordering, sampling and quality control
Sampling is fast: A4 hand feel cards, laboratory dips and a 5 metre trial roll within a week. Bulk runs in 20-25 days, with inline inspection and a final random inspection before packing.

Frequently asked questions
Can we get recycled content with this construction? In most cases yes. GRS certified recycled nylon or polyester can replace the virgin yarn with full chain of custody documents, usually with no visible change in hand or performance.
Can the weight and width be changed? Yes. Most programmes run between 140 and 340 GSM, and width can be set between 150 and 180 cm to match your marker. Changing weight changes cover and stretch, so we re-test before confirming.
